Nuclear Posted March 25, 2009 Posted March 25, 2009 I finally got my water cooling system and new motherboard installed over the weekend. I haven't installed my XP benching image yet, but I did sit down tonight and play with the 940 on the new setup. This chip responds very well to cooler temperatures and the initial results are very promising. On air this chip would do 4GHz at 1.53v. Here's what it'll do on water with 1.475v In case anyone else is interested, here are my quick BIOS settings: HT / NB: 1.8GHz CPU Voltage: 1.475 CPU VDDA: 2.7v NB-CPU Voltage: 1.4v DRAM Voltage: 2.1v HT Voltage: 1.3v SB Voltage: 1.3v This chip should do 4.2-4.3GHz on water without much tweaking based on my initial results and what I have seen with the 7+ 940s I've tested. After I find the max it'll do on water I'll begin tweaking the HT and NB speeds to the highest at the given clock speed. My OS is crap right now so I'm waiting to run the benches after I find my sweet spot and have loaded my good image. Feel free to ask any questions and I'll keep this thread updated with all of my results as I get them. Share this post Link to post Share on other sites More sharing options...
scr4wl Posted March 25, 2009 Posted March 25, 2009 Good job :thumbs-up: How hot is it running? Share this post Link to post Share on other sites More sharing options...
Waco Posted March 25, 2009 Posted March 25, 2009 That's a nice difference simply from moving to water. Share this post Link to post Share on other sites More sharing options...
Nuclear Posted March 25, 2009 Posted March 25, 2009 Good job :thumbs-up: How hot is it running? At 1.475v all 4 cores idle around 32C and load around 40C. That gives me plenty of headroom to up the voltage and gain some overall speed. Share this post Link to post Share on other sites More sharing options...
The Smith Posted March 26, 2009 Posted March 26, 2009 At 1.475v all 4 cores idle around 32C and load around 40C. That gives me plenty of headroom to up the voltage and gain some overall speed. Yeah I'm using the Cooler Master V8 on my Phenom IIs and I also noticed the difference between idle and load temps is not much... Much less than what I'm used to on Intel chips... Hopefully I will get some time soon to put them under dice Share this post Link to post Share on other sites More sharing options...
